Before HST, for a typical residential inground pool. Big pools, custom liner patterns, step or track repairs and hard-to-reach leaks push prices up. Ranges where published GTA and Ontario sources overlap, checked November 2026. Not a quote.

Rebates, permits & rules

Gas pool heaters must be installed and serviced by a TSSA-certified gas technician. Ask for their certificate number.
Electrical work on pumps, heaters, lights or bonding must be done by a Licensed Electrical Contractor, who files an ESA permit. Ask for their ECRA/ESA licence number.
In Toronto, a new or replaced pool fence or gate needs a Pool Fence Enclosure Permit, and you need a zoning certificate ($214.79 in 2026) before you apply. Other GTA cities have their own pool enclosure rules.

What a complete quote includes

If any of these aren't on your quote, ask. Missing doesn't mean it's wrong, but it should be in writing.

What failed, and how they found it (leak test, pressure test, dye test)
Exact parts: pump brand, model and horsepower (single, two or variable speed)
Liner: thickness (mil), pattern, and whether the price includes wall foam, step or track repairs
Water: draining, refilling and who pays for the water
Heater: gas or heat pump, BTU size, and the gas or electrical connection
TSSA gas technician for gas work; Licensed Electrical Contractor and ESA permit for electrical work
Removal and disposal of old equipment
Startup, water balancing and a test run after the repair
Parts warranty and labour warranty, in writing

Watch out for

“Leak found” with no test method or location
A full liner replacement quoted without checking whether a patch would do
Gas or electrical work with no licence or permit mentioned
No price for draining and refilling
Large deposit for a repair that's a few hundred dollars

Repair or replace?

A single tear in a liner under about 10 years old is usually a patch.
Faded, brittle or wrinkled liners with several leaks are due for replacement.
Pump making noise or leaking at the shaft? A seal or bearings repair is often enough.
An old single-speed pump with a failed motor: replacing it with a variable-speed pump costs more upfront but uses less power.
Heater over about 10 years old with a cracked heat exchanger: replace it.

Who does the gas or electrical work, and will you pull the permit?
What warranty do I get on parts and on labour?
